Wrong part- return was a hassle
The A1 staff was friendly and helpful but the return for “their� mistake was a hassle. Again the staff was helpful but I believe their return policy fails to meet basic customer service. I Ordered the part as stated on their website but it wasn’t the right part. A1 staff admitted this part was a problem before but I guess the website hasn’t been updated. They agreed to return my money but only after I returned their wrong part. The part was like $50 dollars and took a full week to get; I ordered the correct part from a comparator and received it in two days. A1 sent me a UPS return label but it wouldn’t print out so I had to drive it to the nearest UPS store 25 miles away. I now have more time and money in this 02 sensor then I paid for it. I guess I expected to be credited sooner and maybe just keep the part instead of having to spend so much time/effort returning it. For the record I can’t use the part so keeping it wouldn’t do me any good other then avoiding all my running around. After all, it was their mistake (and not the first time with that part) not mine and I took the full debt. First time A1 user, very disappointed. I’ll give A1 one more chance only because I believe they deserve it. Frustrated customer
